Question

Which oxide is an excellent insulator for Silicon (Si) fabrication?

Options

• \[\mathrm{CdS}\]

• \[\mathrm{InP}\]

• \[\mathrm{SiO_2}\]

• \[\mathrm{GaAs}\]

Answer 1

Silicon's oxide, \[\mathrm{SiO_2}\], is an excellent insulator for fabrication. This is one reason Silicon is preferred over Germanium in most devices.
